It may be the season of chestnuts roasting on an open fire, but most of us otherwise prefer to keep our fires screened. Leave it to a designer and an architect, both working out of Los Angeles, to introduce fireplace screens this season that get the job done in vastly different styles.

From Philip Nimmo's Ironworks collection of lighting and furniture comes the Oceana, a glass work depicting waves in shades of blue, and the more ornate Cameilia (at right), with a floral design inset with glass of blue, brown, yellow and orange. Both screens are wrought iron and retail for $7,750. (Sloan Miyasato in the San Francisco Design Center is the local representative or go to www.philipnimmoironworks.com.)

Architect Alla Kazovsky worked at the other end of the design spectrum, trying to "create an elegant and timeless replacement to the age-old product of the past." As she notes: "The outcome is simplistically bold." Her Naum screen (at top) combines stainless steel bars and steel mesh in a manner befitting a contemporary loft space. It retails at $830, at www.DesignedRealEstate.com.
